Data corruption is the accidental change of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software failure, and as a result, a file could become partially or fully corrupted, so it'll no longer function correctly as its bits will be scrambled or missing. An image file, for instance, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When this kind of a problem occurs and it is not noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that is a part of a RAID array where the info is synced between various different drives, the corrupted file will be copied on all the other drives and the damage will be permanent. A number of frequently used file systems either don't offer real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common problem on web hosting servers where huge volumes of info are stored.
No Data Corruption & Data Integrity in Hosting
The integrity of the data which you upload to your new hosting
account shall be ensured by the ZFS file system that we take advantage of on our cloud platform. Most web hosting service providers, including our company, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the exact same information is synchronized between the drives all of the time. When a file on a drive becomes corrupted for whatever reason, yet, it's likely that it will be copied on the other drives as other file systems don't feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be swapped with a good one from another hard disk. Due to the fact that this happens right away, there's no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption as all our storage servers employ the advanced ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it will be stored on several redundant drives in a RAID i.e. the files will be the same across all disks. All the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, so if it registers a mismatch, that will indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other drives. Even if there is a sudden power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to get back online. ZFS is the file system which can truly protect your content from silent data corruption.
